Its only practice work but I NEED the extra points. These are the problems I am having trouble with:
(9*10^4)
(8*10^6)
(9*10^4)(8*10^6) = 72^10^10 = 7.2*10^11
Thx this helped!

To solve the problems (9*10^4) and (8*10^6), you need to understand the concept of exponentiation.
In scientific notation, the number is written as a decimal between 1 and 10, multiplied by a power of 10 (which is represented by the exponent).
Let's break down each problem step by step:
1) (9 * 10^4):
To solve this, start by multiplying 9 by 10^4. The exponent means you need to multiply 10 by itself 4 times.
10^4 = 10 * 10 * 10 * 10 = 10,000
So, (9 * 10^4) = 9 * 10,000 = 90,000.
2) (8 * 10^6):
To solve this, again, start by multiplying 8 by 10^6. This time we need to multiply 10 by itself 6 times.
10^6 = 10 * 10 * 10 * 10 * 10 * 10 = 1,000,000
So, (8 * 10^6) = 8 * 1,000,000 = 8,000,000.
Therefore, the answer to (9*10^4) is 90,000, and the answer to (8*10^6) is 8,000,000.
